Quantum metrology, part of the emerging field of quantum technologies, is an extremely promising field which uses quantum mechanics to realize high resolution measurements.
This includes magnetometry, atomic clocks and measurements of weak classical forces to name a few examples. The most important challenge in quantum metrology is to decouple the quantum sensor from the environment while maintaining the coupling to the probe. The field of quantum metrology currently experiences an exponential improvement of e.g. the frequency accuracy of optical clocks and growing activity in magnetometry. Progress in this field has also been stimulated by the success in quantum information processing.
A central role in the field of quantum information is held by the entanglement, which quantifies the quantum correlations between two qubits. A major challenge in creating entanglement is that interaction with the environment creates noise which tends to destroy it. The most important challenge in quantum information is therefore to decouple a quantum bit from the environment but at the same time maintain as strong a coupling as possible to the other quantum bits.
At first sight these two requirements seem to be contradicting. However, the effort to solve this contradiction has created an extremely successful field of dynamical decoupling
As it is evident that these two fields are intimately related, this research proposal aims to combine the theoretical knowledge from quantum information processing with the experimental capabilities of quantum metrology, in order to unleash the synergy between the two fields and to design and realize schemes for the benefit of both disciplines. The main results of IonQuanSense would be high fidelity quantum simulators, high sensitivity magnetometers and precise atomic clocks.
